The World Cup in Russia is less than four months away and a number of Watford players will have their eye on the tournament.

There are players in the squad who know that, barring serious injury, they'll be on the plane to Eastern Europe come early June.

As well as those definite picks, plenty of the Golden Boys will be hoping to make an impression on their national managers and force their way into contention ahead of the tournament.

We've had a look at all the Watford players who could feature in Russia come summer.

The Definites

Andre Carrillo

The Hornets winger is a definite for Peru's World Cup squad, barring serious injury, although there is a chance he will have played his last game for the club by then, given he's only on loan.

After missing a year as he was suspended by his club (Sporting Lisbon), Carrillo has featured in 11 of Peru's last 13 games.

He'll certainly by one of the 23 Peruvians picked to represent their country at their first World Cup since 1982, after beating New Zealand in the play-offs last month. Peru are in Group C with Australia, France and Denmark.

Carrillo will be a little worried at his lack of game-time since Javi Gracia came in, especially as Dodi Lukebakio was brought on ahead of him at West Ham. But that shouldn't harm his chances.

Amrabat is on loan at Spanish side Leganes for the entire 2017/2018 season, but he'll still be Watford player in June.

The winger has played 31 times for Morocco and the only squad he was absent from in the past two years was back in March, when he had a foot injury.

Morocco are in a difficult group, having to play Portugal and Spain, as well as Iran.

The Maybes

Christian Kabasele

Kabasele has been in Belgium's past two squads, but that is mainly due to injuries to other centre-backs.

Spurs' Toby Alderweireld and Manchester City skipper Vincent Kompany both missed out and Kabasele was called in as back-up.

But he is certainly in Roberto Martinez's thoughts and his displays at the heart of the Hornets' defence would have stood him in good stead, however, Kabasele's hamstring injury has come at the worst possible time.

If he is not available to be selected for the March friendlies, it could seriously hamper his chances, especially with Alderweireld and Kompnay both back from their injuries.

The Red Devils are in England's group, along with Panama and Tunisia.

Nathaniel Chalobah

Chalobah's injury has made his chances of making England's squad more difficult.

The 22-year-old was called up to the senior squad at the start of September, for the games against Malta and Slovakia, but didn't make his debut.

Just three weeks later, he hurt his knee in training and has not played since.

Chalobah is yet to return to training and he will not be picked by Gareth Southgate if he hasn't played regularly in the final two months of the season.

The Hornets' midfielder is definitely a player Southgate likes, in a position England aren't too strong in, but the fractured kneecap could end his World Cup dreams.

If he does make it, there's a chance he could come up against Kabasele, with the two countries in the same group.

Gerard Deulofeu

The January signing is a new name on this list and he goes straight into the hopefuls category.

Gerard Deulofeu has stated that his intention is to break into the Spain squad and he'll know that good performances at Watford will make that happen.

Deulofeu was picked in three successive squads last year, on the back of his form at AC Milan, before dropping out of the side in October and November.

The Spanish national side is hardly the easiest to break into, with a vast array of talent, but Deulofeu has the ability.

Spain will play Morocco, Portugal and Iran in Russia.

Richarlison

When we first had a look at the players who could feature in December, it felt like Richarlison would force his way into Brazil's squad.

Since then, Richarlison has struggled for form, failed to score and looked in need of a rest.

Whilst he did reveal in an interview that Tite, Brazil's coach, has been in contact with him over a potential call up, the March international break is only a month away and a call up for Richarlison would be a surprise.

But that doesn't mean he can't put himself in contention in the final throws of the season, with Brazilian journalists in England still championing his cause.

Costa Rica, Serbia and Switzerland await the Seleção in Russia.

Abdoulaye Doucoure

If Doucoure was English, he'd be in the squad, but there is a plethora of talent in France currently.

Paul Pogba, N'Golo Kante, Blase Matuidi and Adrien Rabiot are just four of the central midfielders ahead of Doucoure, and there are more too.

But, given his form, Doucoure's ambitions are not misplaced. He's certainly performed better than Tiémoué Bakayoko in the Premier League and his performances won't have gone unnoticed.

He played for France at youth level and if Doucoure continues to take the Premier League by storm, he'll be in the reckoning.

Doucoure has mentioned the national side in recent interviews with French media too, so it's clearly on his mind.

The 25-year-old could come up against Carrillo if he does, as France are that group with Denmark and Australia.

Isaac Success

Nigeria coach Gernot Rohr offered an olive branch to Isaac Success last month - and Ahmed Musa, ahead of his move away from Leicester - saying that they would be considered if they played regular football.

Success made his debut for the Super Eagles last March, pulled out of their squad in June, which caused some controversy, and his lack of club football has hardly helped his cause.

Reports in Spain suggests he needs to lose weight before Malaga coach Jose Gonzalez considers the loanee for a start and time is running out for the 22-year-old.

The Super Eagles already have five friendlies confirmed before the World Cup, so there are plenty of games for Success to prove he should be involved, if he gets the nod.

If he does make it, Argentina, Iceland and Croatia await - not an easy group.

The Long Shots

Will Hughes

The 22-year-old started to pop up in 'could he go?' conversations before he injured his hamstring, after a number of impressive displays.

But his injury has kept him out since November and there is next to no chance now of him slipping into Gareth Southgate's thoughts.

If England's midfielders suffer a large number of injuries over the coming weeks and Hughes secures a regular spot at Vicarage Road, it might happen, but that is a real long shot.

Hughes needs a lot more top-flight football under his belt before he makes it.

Tom Cleverley

As much as Watford fans would like Cleverley to get another chance, it seems improbable.

Cleverley was in Southgate's thinking for the last squad, but did not get the call-up.

That was at a time when England's squad was decimated by injuries, but Cleverley was still not named in the squad.

His has not performed at the same level since then and injuries have also begun to take their toll.

Even if his form improves, don't expect Cleverley to be on that plane.

Kiko Femenia

Watford's right-back has been immense this season and would be plenty of teams' starting right-back.

Unfortunately Kiko is Spanish and they have plenty of quality in almost every position.

Had Kiko avoided injury and continued to perform as well as he was, Julen Lopetegui may have had no other choice but to give Kiko chance.

Now, it may mean that he is relying on others' misfortune to get on the plane.

Roberto Pereyra

Another player with bags of quality, but one who is unlikely to make Argentina's squad given his recent form.

The last of Pereyra's ten caps came in October 2015 and he has not even been named in the squad since then.

A strong finish to the season with Watford could bring his name into conversations, but that is likely to be it.
